DOUBLE PILE FABRIC Filed March 27. 1928 "Patented Mar. 3, 1931 PATENT OFFICE J' OHN ZIMMERMANN, JR., OF OAK LANE, PENNSYLVNIA h DOUBLE-PILE FABRIC Application tiled March 27, 1928. A Serial No. 265,130.

My invention relates `to double pile fabrics, that `is to say, to fabricswhich are woven with two ground weaves, and having pile forming warps extending therebetween which are substantially cut for the purpose of producing two separate fabrics, each having a pile face.

The principal object of my 4invention is to provide animproved double pile fabric which, when cut apart, will produce two rugs or carpets, each of the well known ,"Wilton type. f

A further object of my invention is to provide a fabric of the type aforesaid, which may be rapidly and economically woven in a double shuttle loom whereby the weft shots may be inserted simultaneously in both the upper and lower weaves. j

A further object of my invention is to provide a fabric of the type aforesaid, in which the pile tufts will be securely held in the ground weaves after the same are cut apart.

A further object of my invention is to prox` vide a fabric of the type aforesaid, in which the dead ends of the figuring warp will be evenly distributed in the ground weaves, whereby the same Will be of a uniform texture, and this notwithstanding that a certain color or colors may predominate in the pile.

A further object of my invention is to provide a fabric of the type aforesaid, whereby seamless Vilton rugs of the larger or room sizes, may be more economically produced `than heretofore.`

j lVith the foregoing objects in view, my invention contemplates the. provision `in a double pile fabric of upper and lower ground weaves each having three corresponding shots of weft between each crossing of the binder warp, the carrying of the pile forming warp from the one ground weave to the other to form the pile, and' the binding of the pile Warp in the ground weaves in such manner that the same will be securely held therein.

The nature and characteristic features of my invention will be mo-re readily understood from the following description, taken-in con nection with the accompanying drawings forming part hereof, in which Y ,50 Figure l is a longitudinal section of a double pile fabric embodying the main features of my invention, illustrating the ar rangement therein of one set of figuring warps; and

F ig. 2 is a similar view, illustrating the arrangenientof an adjacent group of figuring warps.

Referring to the drawings, in the particular embodiment of my invention therein shown, the double pile fabric comprises two f ground weaves, each consisting of pairs of binder warp l and 2, and three shots of weft, 3, 4 and 5, respectively, between each crossing of the binder warps. i

ln the preferred manner of weaving the double pile fabric, a double shuttle loom is employed, and the shot designated 3 in the upper ground weave is inserted simultaneously with the shot designated 3 in the lowerI ground weave. In lilemanner the shot designated 4 in the upper ground weave is inserted simultaneously with the shot designated 4 in the lower .ground weave, and the shot designated 5 in the upper ground weave is inserted simultaneously with the shot designated 5 in the lower ground weave. This is rendered possible by the peculiar' composition of the weave. It should also be noted that the weft shots 3 lie in the outer planes of their respective ground weaves, and the o shots 4 and 5 of each ground weave lie in the inner plane thereof.

For the purpose of forming the pile, the figuring warps are carried from the one ground weave to the other, and back again. In the drawings, there is illustrated a typical arrangement of the figuring warps wherein the saine are arranged in groups or sets of color ends, and in one group or set (see Fig. l) there are three differently colored figuring wai-ps 6, 7 and S, which are primarily carried by the upper ground weave, and three other differently colored figuring warps `9, 10 and l1, which are primarily carried by the lower ground weave. This arrangement will ordinarily be provided in a single dent space of thev loom in which the fabric is woven.

` In the next adj accnt group or set of color ends, (see Fig. 2) the corresponding {igur- 5' lthe saine passes into lthe ;pile region, fron between the 'inner and outer planes of the ground weave where it has beencariiedfas a dead end, passing .between .-,t-he weftsgnuin- ,bered 4 and 5 of a particular shedding, thence over .to the other ground weave,.xwhere it passes between thev wefts numbered 4 and 5 the ,only ones illustrated as being carried over ofthe corresponding shedding ofthatground ,veave, thence between the. inner and .outer planesof the wefts of .that ground weave, thence. returning 'toV the .original ground weave from which itwas taken, passing betweenthe .wefts numbered 4l and 5 ofthe next shedding, and repeating 1n 'like manner .as

Vlong asthe particular color is required in the face of the pile. y l

."Whenithe c olorchanges, the warp which vhas been t usedl in `the pile forming `as aforesaid is thereafter. carried as a' dead end ibetween 'the inner ,and outer ,planes of the weft brought out 'and'in like lmanner'carried across from the one. ground fabric to the other, so that lthe saine will 'appear inthe face of the pile. v Y A' Vfhile, inthe drawings', the warpends i are from one ground weave to the other, and

kback again, it Will., of course, be understood thatfthe other figuring warps, namely, 6,19,

ltlfand ll, are in like manne-r vcs nried.over

1 whenever their respective colors are usedin the pile. 1

. lt -sl'iould be noted, however, rthat foi-the Y' best results the figuring war-p which has been carried over to foi-an the pile wi'll be finally returnedto the grou-nd weave from whichit canne, and is thereafter carried in said ground weave asa dead end, and in .this manner the distribution of the yarn 'between the two ground weaves will :be balanced and thc'tex- 'tu re lie kept even tlujowughoul l l It will, lof Course, `be understood .that 'the number of pile forming warps carried by the .respective Vupper and lower ground weaves will'gbe .considerably Varied' in practice, ac-

cording Ato, the requirements of the pattern, etc. A

Itwilfl, alsobe ,apparent t.hat,'if desi-red,

stufferwarps maybe used in addition tothe figuringwarps, for the purpose of giving additional body to the ground weaves. It has not been :thought necessary tov illust-.rate such stuffer warpsfas' thefsanie are not essential tothe weave, and in most cases would be omitted entirely. f

= It will be vseen that by the present inven-l tion there isprovided a fabric ofthe double pile type, adapted to be cut apart in the usual y be equally' desirable and of uniform texture and weight throughout,'jinwhich the pile tufts will" be securely'bound inthe ground YAweave, Aand which may be woven in Widths ,for the production of :the larger or rooin size seamless rugs.

Having; thus described the nature and characteristic features of iny invention, what I claim as fnewand kdesire to secure by Letters Patent, is: y Y
